Importance and distribution
Biochemical importance of the genus, chemical diversity or applications
Poch and Gloer (1989) reported Helicascolides A and B which are lactones derived from the marine fungus Helicascus kanaloanus. Jones et al. (1997) mentioned that H. kanaloanus has the ability to decolorize the polymeric dye Poly-R478 and Azure blue (lignin model compounds) using glucose or crystalline cellulose as a carbon and nutrient source. Helicascus comprises eleven species known on Aegiceras corniculatum (Primulaceae), Alnus glutinosa (Betulaceae), Avicennia alba (Acanthaceae), Nypa fruticans (Arecaceae), Rhizophora mangle (Rhizophoraceae) and Sonneratia apetala (Lythraceae). Helicascus is known from Africa (Egypt), Asia (Brunei, China, India, Malaysia, Thailand), Australia, Europe (France (Martinique)) and The United States (Hawaii).
